Antimicrobial Resistance

Antibiotic resistance is the ability of microorganisms to grow despite exposure to antibiotics. As a result, the bacteria remain in the body, causing the disease to spread to others. There are several biological and social causes of bacterial resistance.

antimicrobial resistance mechanisms

Microorganisms that acquire resistance are sometimes referred to as “superbugs”. As a result, the infection is not eliminated from the body, which increases the risk of spreading it to others.

Causes of Antimicrobial Resistance

The most common cause of resistance is the increased use of antibiotics. With the use of antibiotics, few bacteria become resistant. This gives them a chance to develop and grow and makes the individual more susceptible to infection.

Apart from this, there are several other factors that contribute to bacterial resistance. Some such issues are discussed below.

Biological Causes

In the presence of antibiotics, microorganisms are killed or survive if they contain resistance genes. These will reproduce and become dominant throughout the microbial community.

Microorganisms disintegrate within hours. They grow quickly and adapt to new environmental conditions. During division, mutations occur in some bacteria and some mutations become resistant to their antibiotics.

The way people use antibiotics contributes to the causes of resistance. Some of the social issues are discussed below.

When a course of medication is not completed, some bacteria become resistant to the medication and stop responding to it. Also, if you take medicines for chronic infections, microbes develop resistance.

Examples of Antimicrobial Resistance

Tuberculosis was a major threat before antibiotics. Drug-resistant strains of tuberculosis have emerged recently. These types of infections do not respond to conventional antibiotic treatment. Drug-resistant tuberculosis is very difficult to treat. Bad management can prove fatal.

It is a sexually transmitted infection caused by bacteria. Recently, cases of drug-resistant gonorrhea have come into focus.

These bacteria are responsible for foodborne illnesses and urinary tract infections. Cases of antibiotic resistance in E. coli are increasing rapidly.

In many parts of the world, drug-resistant malaria parasites have evolved to become resistant to these antimalarial.

However, scientists have come up with other ways to overcome the disadvantages of antibiotics. For example, the development of viruses that can eat bacteria, the development of vaccines, and the use of probiotics to restore the intestinal microbiota.

Antimicrobial Resistance- A Global Concern

New resistance strategies are spreading around the world, threatening our ability to deal with infectious diseases. This led to his prolonged illness and death. Medical procedures such as organ transplantation and chemotherapy have become more dangerous due to the lack of effective antibiotics. Antibiotic resistance is life-threatening because it requires aggressive treatment.

This is a common problem caused by several interrelated factors. National action plans are needed to address antimicrobial resistance. Antibiotics and vaccines must be found.

The World Health Organization also provides technical assistance to countries in developing national antimicrobial resistance action plans. It works closely with FAO and OIE to provide best practices to avoid resistance.
